IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 4I IA7I, dated February 9, 18.34.

To all whom it may concern? Be it known that I, RoBERT D. Baowmof (Jovington, Fountain county, Indiana, haveinvented a new and useful Improvement in Harvesting-Machines; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawing making part of this specification. 4,

My intention relates to devices for enabling the employment-of a selt' rakingaudigavelingapparatus, in connection with a floating plat} .form and sickle.

Figure 1 is a perspective view of m yim'prove- "me'nt, together with portions of a harvester im 'mediately connected therewith. Fig. 2 is a top view of my swiveled coupling-rod.

I The main frame A is supported on customary ground wheels, B B, from whose axle U .the various operative parts may derive their motion in-auy approvedwa-y.

Dis the platform-frame,connected to the main frame by means ofswiveled coupling-rod E and drag-bar'F. Th'e drag-bar. F projects rigidly forward from the platform-frame, and engages hy means of a hook,f, in the outer extremity of an arr'n,-G,'which at its other extremity is hinged to the main frame. A. perforated 'bracket,H, attached tothe. main frame, and a holt, I, enable the arm G to be set at a greater or less elevation. The connection of the rod E to the main and platform frames respectivel is made by meansot' gimbal or universal joints, in manner substantially as follows:

- e and c are sleeves which embrace shafts J and J, jourualed in the main and platform frames, respectively. Theshat't K ofthe crank.

L, which operatesthe sickle-pitlnamaliay derive motion from the mainax eU in the'usual way. Affixed to the shaft K is a pinion, M,

whichgears into a spur-wheel, N, on the shaft 3 V Upon the shaft'J is a sliding pulley, O, which? can be coupled withthe wheel N by means of a clutch, P. Treadles Q Q enable the clutching and unclutching of the pulley- 0. The pul-- ley O communicates by'chain or band B with a pulley,S, which-is fast to the shaftJ, jour n'aledat the inner end of the platform.

may be accomplishedhy a con tinuously-revolving'rake, substantially such as'descri'hed' in Letters Patent granted to me on the 7th day of April, 1863. The endless rake is attached 'uptips the cradle.

The removal of the-grain from the platform to andcarried around by belts or chains TT,

stretched around pulleys j j onfthe shaft J at the inner end of the platform and pulleys .u to

cattle shaft U at the outer endof theplab form. A'jog, d, in therear edge of the fingerbram enables the pulley u to he placed so far 'forward as to bring the rake close behind the sickle. Prolongations d d of the innerend ofthe.plattorm-frame carrj the-shaft V of my f intermittent cr'adleV W. The forward end of theshaft'V carries pinion 'v. A pinion, X, up-

on'the shaft J meshes with a wheel, Y,"which vcarrie's'acogged cam, y, which ateach rota'- tion of the wlieelYmeshes in the piniono'and In arranging the endless rake and intermittent'cradle care is required that the instant of uptipping of the cradle shall occu-r justas onetierof rake-teeth hasdeli'vered its load and before the nextfollowing tier has; come forward, so that no grain-may be spilleclnapon the ground during the lift of thecradle; v

I claim herein as new and of my invention-s- 1. The mode, snbstantially'as described, of

connecting the platform to the main frame by the swiveled coupling -rod E, sleeves e e, and

shafts J and J, whereby motion can'be. communicated to the ralrooon erfectly-floating platform without atfectingthe continuity of the raking motion or straining the parts.

' 2, In.the'descrihedcomhination with a float}- ing platform,endlessrake, and swiveled coup- -ling, the chain R and pulleys O and S, or equivalent flexihle'device for transmitting motion to the raking mechanism, as set forth.

3. In thedescribed combination with a swiv el'ed' coupling, E e c- J. J, the device for vary ing the pitch of the cutting apparatus, consi st-.

ing ot'the drag-bar F f, bracket H arm man-u pin'l,' or their equivalents.

..4. The arrangement of the outer and for- .ward endless rake-pulley it within a recess, '01-, in the-rear edge of the finger-bar, soasto
